基于SOC单片机的高集成度光电编码器电路设计
资料介绍
提出了减小光电编码器电路部分空间,缩小其结构尺寸的方法,并对编码器的电路处理进行了研究。介绍了光电编码器的基本原理、光电信号特点和信号处理的要求,分析了传统电路处理方案的特点,说明了基于放大器和比较器的传统方案是造成电路结构设计体积较大的原因。为改变传统方案,提出了用AD直通处理和分时驱动光电信号采集技术来代替传统硬件设置从而有效压缩电路部分空间的方法。介绍了编码器高集成度电路设计的实现原理,并设计了一种16位小型编码器,其电路板面积为415mm2,,编码器体积仅为Ф25mm×16mm。设计实验表明,基于SOC单片机的高集成度光电编码器电路设计技术使用元器件少、电路简单、集成度高,可有效压缩传感器电路部分的空间。
A circuit design method was proposed to compress the space of circuit in a photoelectric encoder and to reduce its size,then the signal processing of the circuit was studied.The basic principle,signal characteristics and signal processing requirements of the photoelectric encoder was introduced and the characteristic of traditional process circuit was analyzed.It points out that the traditional scheme based on amplifiers and comparators is the reason that the circuit structure is larger.To improve the traditional scheme,the methods of A/D through processing and time sharing driving photoelectric signal acquisition were proposed to ...
